Review leopardstown 27th Jul

< The Pentagon gave Aidan O'Brien his 11th victory in the JRA Tyros Stakes to advertise his 2018 Derby claims at Leopardstown.

The Ballydoyle handler has used the Group Three as a stepping stone to great things for the likes of Rip Van Winkle, Gleneagles and Churchill, and The Pentagon was a red-hot 4-11 favourite after running away with a Curragh maiden at the Oaks meeting.

He was more workmanlike on this occasion, taking his time to get to the front in the straight, but there is plenty of stamina in his pedigree and the further he went, the better he went as he scored by a length and three-quarters from Theobald < Happily showed plenty of the family talent to stride away from her rivals in the other Group Three on the card, the Jockey Club Of Turkey Silver Flash Stakes.

O'Brien's filly is a full-sister to the yard's Classic winners Gleneagles and Marvellous and looks destined for big things herself after strolling home five lengths to the good over Shalailah as the 8-11 favourite.

The O'Brien-trained Delano Roosevelt (14-1) made a successful start to his career by overturning his short-priced stable companion Coat Of Arms in the Frank Conroy Irish EBF Maiden.

The odds-on favourite looked home and hosed when kicking clear after the two-furlong pole, but Delano Roosevelt, a Galileo colt out of Irish 1,000 Guineas heroine Again, wore him down to claim the spoils by a head.

Jockey Wayne Lordan followed up on Paul Deegan's Magwadiri (12-1) in the Stunning Handicap, while O'Brien went on to complete a four-timer when 9-4 shot Belgravia fought hard in the Horse Racing Organisation Of Greece S.A. Race.

For most of the home straight, Ballot Box looked likely to make all in the Irish Stallion Farms EBF Claiming Race but Island Affair (12-1) lunged late and got the verdict by a head.< Temasek Star (7-1) had done all of his winning on the all-weather prior to the SOREC Morocco Handicap but dug deep to triumph.
